@ne of 'the important purposes ot. this invention is -to 'simplify themeans hitherto proposed to raise and' lower the frame and ground workingelements of a tillage imple- 'ment by power derived from the tra-vel ofthe implement and which means will nevertheless be most readilyadjustable to produce ditlerent'depths orn furrowslandietective in theopera-tion of raising and lower ing the ground working members out of orinto ground working position. To this end, the implement is providedwith a crank axle which is journale'd to the frame thereotl and 'saidaxle is provided with a'spindle upon which al supporting wheel and aclutch are journaled7 y the clutch having vits driving portion of theaxle relatively to the frame and lground to variably regulate the depthof penetration of the ground working members, the parts being thus socorrelated that the rotative movements of the wheel are impartedvdirectly to the driving` member ot the clutch and thence vto the drivenclutch member, thereby eliminating elements hitherto deemed 'to bevnecessary 'in mechanisms for raising and lowering the Airame and groundworking members by power derived from the travel of the implementwithout eii'ecting the capability of adjustment to produce urrows ofdifferent depths. More particularly defined, this part of the inventionincludes in the connection between the driven member of the clutch andthe frame, ari-,element 'which rotates with the clutch and is capableoft-ranjslating rotative' movement into -up and down movement Vand stillmore particularly definedv the connection consists of an veccentric"rotative within a strap or housing having an arm which is pivoted to'an adjusting lever' and which adyusting lever in turn is pivot-v ed tothev frame and is mounted t'o be yfixed 'by a suitabledea .0r lateh, erthe 'like in 'parts in section.

any one or' a plurality'opositions to la toothed 'segment' orquadrantcarried bythe this invention is to provide connections. whereby the`trout and rear ends otthe 1m-v pleinentf are lowered in a peculiartimedv relation andare raised in a peculiar ytimed relatioi'n'hereiriafter'f'liullyv set forth,V the .connections also being of suchnature that they areradapted to beroperated by torce derived lfrom thetravel of a supporting wheel of VJthe implement. y

In'the accompanyingdrawings I have illustrated one *''orm' otimplementembodying` 'mechanism `-for accomplishing the Vforegoing purposesyand`v'other purposes .which will be apparent, but I' Vwould have itunderstood' that .the invention may be otherwise embodiedwithoutdepartingfrom its spirit as defined by the'appended claims.

In the i'mplementselected to exemplify this invention: two soil turningmembers or" jtlie mold board type are illustrated and the clutchmechanism" is shown ias applied to thefurroa wheel; but I would have itun- .'derst'ood that the 'invention is not restricted `to the number`or-tothe particular kind of soil turning members 'employed 'and 'Iwould also have it 'understood that the clutch implement7 although inthe'specitic type 01"" complete'implement 4illustrated in the drawing,`it vis preferred that the clutch mechanism lbe applied Ato afurroivwheel rather than to the land wheel.

The frame here shown comprises two substantially parallel longitudinalbeams 10, 1()a tied together by a transverse connecting element 11 nearthe rear end and by a transverse front member 11EL andfront cornerbrackets 11blach beam provides a support for a soil turning member ofsuitable kind connected to it in an appropriate manner. In theconstruction shown by way of example in the drawings, each beam has adownwardly bent rear end to which is attached a plow body 12 of thesingle mold-board type.

A, B and C Adesignate the land and furrow wheels which support theimplement. The front furrow wheel A and the land side wheel 'B in theembodiment of the invention, illustrated in the accompanying drawings,are mounted on separa-te crank axles for a purpose hereinafterexplained. The axle to which the front furrow wheel A is connected hasan upper horizontal bearing portion 14, extending across the space.

between the beams 10, a andjournaled in bearing members 15 suitablyattached to said beams.

It also has a downwardly extending crank portion 16 terminating at itslower end in an outwardly extending spindle portion 1?. The axle towhich the land wheel C is connected is of similar construction: 18 (Fig.4) designating its upper horizontal bear-V ing portion which isjournaled in the bear-v bearing members 15 in a clockwise direction, i.e. toward the rear from t-lie position shown in Fig. 1, the crankedportions 16 and 19 will assume a more nearly vertical position, thuselevating the forward end of the frame and lifting the plow bodies, andthat when they are turned in a counterclockwise direction the forwardend of the frame and the plow bodies will be lowered. f course it willbe understood that in the first nam-ed movement thejwheels A and B moverearward and in the otherrmovemenf said wheels move forward. a y

The wheel C which supports the rear end of the implement is mounted torotate upon the lower laterallyextending end 21 of a cranked axle havinga vertical portion 22 which is mounted to rotate in a bearing` 23carried by a bearing member 24 pivoted upon a horizontal axis, at 25, tosustaining` plates 26, 26L securely fastened to the rear end of theadjacent beam 10a. lt will thus be seen that'wheel C has movement withits axle upon a vertical axis in the guidance of the implement, and alsohas movement upon a horizontal axis, about the pivot-25, to raise.l andlower the rear end of the implement to and from transport position, itbeing noted that the wheel C moves forward in raising the rear end ofthe imple.- meut and rearward in lowering the same. ln order that themovements of both wheels ifi and B and their axles may take placesimultaneously from power derived from the motion of one of said wheelsin the forward travel of the implement, applied through a means formingpart of mechanism which (a) also affords provision for a primarysimultaneous adjustment. of said axles and wheels to regulate the depthat which the soil turning members shall work and (o) affords provisionforan independent adjustment of one of said axles and its wheel to levelthe implement and also to normally adjust the depth of plcw ing and inorder further that there shall be a movement of the rear axle and furrowwheel C by power derived from the forward travel of one of the forwardwheels yA or B but automatically controlled in sufxh manner that therear end of the frame shall be raised and lowered in suoli timedrelation to the raising and lowering of the front end f the frame thatthe soil turning members shall leave, but more especially shall enter`the soil point first, l have provided peculiar connections which arefurther characterized by simplicity. effectiveness, durability and theease with which the operations inay be eHected. Vllhile l shallpresently describe these connections in more or less minute detail, I donot thereby wish to be understood as restricting` the invention totheprecise details illustrated as these details 'may vbe changed withoutdeparting lil@ from the spirit of the invention or the scope oi'appended claims.

It is preferred in practice to utilize the furrow wheel A as the wheelfrom which the l)ower for raisin@- and lowerin the im leis rotatablymounted on the axle spindle 17,

and means of any suitable nature are provided for locking this member-tothe driving member 27 and for releasing it thereby way or" example. Itcomprises two crank shaped members having outwardly extending arms 30,31, respectively pivoted at their inner ends within the member 29. Thepivots are marked 30a, '31a and are on opposite sidesof the spindle 17and the members are i connected with each other bya link 32 whosevopposite .ends are pivoted to the shorter arms or' the members. rlvhearm 31 has a lateral projection 33 forming a pawl to engage the teeth 28in the driving member. A. springr 3e is provided to urge the arms to theposition they occupy when the pawl 33 is engaged with the teeth 28. Thecasing of the driven member 29 is shown as having a ,cir-

cumterentialtlange 35 formed at the places marked 36, 36a withoppositely disposed openings through which the arms 30, 31 eX- tend andadjacent to said openingsV it is ver 42 connected to the 4latch 39 andprovided with a rope or cord 4:3 extending to within convenient reach ofthe operator "on the` Y tractor, (not shown)v constitutes a suitable ili) means by which the latch 3'9 may be manually operated to disengageits projection 38r nromthe adjacent arm 30 or 31. It will be understoodthat the projection 38 isnormally engaged with one oit the arms 30, 31'so that the pawl'33 `is normally disengaged 'from the teeth `28, andthat when it is dej, sired to utilize the'power means for lifting thesoil turning members to transport position, or for lowering them toworking position in the soil, the operator on the tractor V'pulls uponthe cord 43, thereby 'inovingthev mlatch 39and disengaging theprojectionsV 38 from the adjacent ar'm'30 or' 31, whereupon thes-'pring'34 becomes operative to' engage the pawl 33 with av tooth of theldriving inember l2,7,` thereby locking the .driven'member 29tofthef'dlvng Vn-.ie'inber and-"hence to the 'furrowfwheel A. As `soonas this has been done the operator ceases to pull upon the cord4t3fwhereuponthe lever 42 and the trip latch 39 are-returned to theformer positions-by a spring 42a. Thefforward mo-v tion of thewheel A'now causes'the drivenk member 29 to. turn, in the directionotthe arrow,Fig.. 3, one-half revolutiomnear the end ot zwhich movement theoutwardly' projecting yendfof the arm 31 (assuming that theimplementlwas in transport position and is vto belowered to working'position, in which case arm 30 is the one which was released at thebeginning of the operation) comes'into engagement with the projection.-L

38 and held thereby, a slight further move- .y ment oi' the member 29bringing its recess from, at will. One such means is illustrated 37aintofull registration with the projection 138, whereupon the projection 38becomes fully seated in the recess.` 'lt will beunderstood thatwhen arm30 was released, spring 3Ll-became operative to force pawl 33 intoengagementwith a tooth oia the driving member of the clutch and duringits operation also imparted movement to the arms 30, 31 so thattheyextend across the openjection38 and are pressed back betere saidprojection becomes seated. During this slightturther movement, the pawl33 is withdrawn from its' engagement with the teeth 28 and the spring 34is placed under tension. It ,w'illlbe noted thatl thev projection 38rides upon the edge of the member 29 when the latter is rotating and.that sai'1 edge is lformed with high parts 44, t on opposite sides ofeac-h opening 36, 36a and that the outer end of each armV 30, 31 issomewhaty offset, to expedite the operation of disengaging thepawl fromthe vdriving member. i' Y l/Vhen" the soil turning members are 1n withthe arm 312v When the frameand soil tui-ning members are to be raised totransport positiom'the operator' again pulls upon the cord, therebydisengaging projection. 38

from arm 31 allowino' the s rino' 31ta fainv v 7 n a a to: engage pawl33'withratchet 28, whereby clutch memberl 29v will again ,turn one-haltof a revolution, at the end of which movement lprojection-*38 willengage arm 30,@

turning members in' an upward or downward direction, through theconnections which will now be described .and-which'constitutel importantparts ot myl improvements.: f

Suitably fixed to the zdrivenlleelber 29 'working position thev latch.projection 38 will be-inthe recess 37a and in engagement 4 Y Y inname iseccentric 45. lt is shown as secured to the driven member 29 at 46 andhas its hearing upon the spindle 17. ltY turns within cam strap 47having` a projection 48 to which is attached the lower end of an arm d'9whose upper end is pivoted at'l9a to an a ljusting lever 50 whose upperend is within convenient reach ot the operator on the tractor. Thislever is pivoted at 50a' to a bracket 51 which is `fixed to the adjacent4beam 10. lt is provided with a latch 52 to yengage any one of the teethoit a fixed segment 53 and this latch in practice is provided with asuitable operating handle within convenient reach ot the operator on thetractor. Thus, the lever may be manually adjusted to and iixed in, anyone oi' various selected positions. These adjustments o'i the levei`vary the angle to which the crank portion ot the axle is set withieterence to the traine and ground. lt will be noted that in this manualadjustment, the eccentric 45, strap e7 and r9 move as a unit about theaxis and that the axle swings in its bearings in the traine, thedirection of its swinging movement being forward or rearward accordingto jthe direction of movement given the lever 50.` During this operationthe clutch members are disengaged trom each other and the wheel A runsfree on the axle spindle 17. But in the operation of raising or loweringthe' implement by power derived from the forward travel ot theiinplement, the lever 59 substantially lorms a fixed partv ot the trame,the eccentric 45 rotates with the wheel A and within the eccentricst'rap 4:7 and said strap and arm turn upon the pivot 49a. It will beunderstood that the highl part ot the eccentric l5 will be upward whenthe parts are in transport position and downward when they are inworking position and that during the travel or" the eccentric from oneposition to the other it exerts force upon the axlev spindleV 17, andturns the axle portion lll in its bearings-the arm i9 and strap *47 inthis movement swinging about the pivot to control the movement of themember'Ql 1 on its horizontal axis in suoli manner that a9, asalreadystated.

The journal portions lll and 18 of the crank axles whichare carried bythe wheels B and A, respectively, are connected with eachother by meansoperative to transmitA raising or lowering movement :trom one ot saidjournal portions to the other and which means includek disconnectibleelements oper-A ative to permit relative movement ot saidv journalportions and to tix one of the vcarrying wheels into dii'ferent selectedpositions with relationv to the other carrying wheel. The particularmeans -now Vto b e described in detail are not herein claimed,

broadly, since it is made the subject 'of a separate application forLetters Patent filed'. as adivision hereof and in response. to alrequirement of division. This means com- `tor said slide.

prises a crank 5l projecting trom the jour'- nal portion le, a crank 57projecting from the journal portion 18; a slide 55, to the rear end otwhich the crank 54 is pivoted at 54a; a lever 59; and a link58l whichconnects the lever 59 with the crank 57. The slide 55 has a segmentaltoothed forward end 56 to be engaged by a rlatch 60, carried by thelevervf59 and having an operating element 60LL which extends to withinconvenient reach ot the operator on the tractor. The leve is pivoted at592L to the forward end of the slide and guides 55a are provided lt willbe seen, therefore, that the lever 59 is adjustable pivotally relativelyto the slide 55 and is also movable bodily back and forth with saidslide. rlhe pivotal adjustment of the lever 59 is to level the trame andto normally govern the depth et plowing, and during this particularadjustment the axle of the land wheel B is swung in its bearing 15 onthe trame backward or forward as the case may be without transmittingmovement to the axle ot the furrow wheel A, tor the reason that thelatch 60 is detached from the slide 55 and the latter remainsstationary. The axle of the land wheel. receives motion from the lever59 through the medium ot the link 58 and vcrank 57, as is apparent, inleveling the frame but in moving the trame to or from transport positionand also in adjusting` the angle ot the crank portion 16 ot the`furrowwheel axle by the lever 50 the axle of the land wheel is swungbackward or orward from similar movement of the Vaxle of the turrowvheel, for the reason that at this time the lever 59 is locked to theslide 55 and partakes 01"' the slidable movement given the latter by thecrank 54E and transmits movement "from said slide to the crank 57,through the medium of the link 58.

rllhe slide 55 also forms an element oip a connection to the rear wheelC, or rather to the bearing member 2li which carries the` axle of saidrear wheel, rlhis particular connection is of a special nature designedot the axles ot the wheels A and B. ln

other words, the parts as so combined that whereas the movements of thewheel C in j raising and lowering the rear end of the implement areunder control of the parts which raise and lower the front end of theA lZlib turning` members are caused to enter and leave the soil at aninclination7 point downward in entering and point upward in leaving.

The illustrated means for accomplishing this very important resultcomprises a link 6l whose forwardend is pivoted at 61a to the slide andwhose rear end is pivoted to the upper end of a lever 62 which ispreferably composed of spaced side members and is provided with a roller64 at its lower end. This lever 62 is pivoted at 62l between the fixedplates 26, 26 and its roller 64 is arranged to traverse a curvebearingsurface 65, forming a track therefor, pro` vided by the rear edge of thebearing member A latch 66 is pivoted at its front end, at 66a7 to abracket 67 fixed to the adjacent beam l0 and its rearendS provided witha lateral projection 68, ,(Fig. 7) at one sid-e of the latch to engagethe upper edge Vof the plate 262i to limit the downward movement of thelatch and a similar lateral projection, 69. to bev engaged by the,forwardly projecting end of a trigger 70. This trigger is carried bythe lever 62 and is preferably adjustably fixed between the side membersof said lever, being here shown as pivoted at 62a and having its upperend provided With a slot 70"1 and a lateral projection 7Gb (see F ig.8).. fastening'jbolt 7l extends through the side members forming thelever 63 and also through an eye formed in the link 6l and through theslot 70a in the trigger and 'forms a pivotal connection between the linkand lever, and at the same time fastens the upper end ofthe trigger tothe lever. An adjusting bolt 72 extende ing through the lateralyprojection 7()b `of the triggerl forms a means for adjustably raisingor lowering the end of the trigger which projects fromthe lever 63. Inthis adjustment of the trigger it turns upon the pivot 62a and its upperend moves relatively to the bolt 71which should be slackened to per-mitsuch adjustment. v

The bearing member 24 is provided with a forward projection 73 whichmoves with it and is arranged at one side 0f the track r with itsforward edge 73L in position to engage the rear edge 66b of the latch66.`

The operation is as follows i In F ig. 5 the parts are shown 'in'transport position. The projection 68 from the latch 66 is resting uponthe rear edge of bracket member 26a, the roller 64 on the lever 62 isengaged with the track 65 and the forward end of the member 7 3 is freefrom engagement with the rear end of the latch. In this position of thelever 627 the trigger is away from the projection 69. The load or weightof the rearendof the' frame is imposed on the lever 62 from' thjebearing member 24. If now it be` desired to lower the frame, the clutchmember 29 on the axle spindle'l'( is engaged with the clutch member 27on the -furrow wheel A andas yalready set forth this causes theeccentric 45 to be turned one-half revolution and causes the crankedportions 16 and 19Y of the forward axles to swing forward and theircranks 54 and 57 to swing rearward and the slide 55 to move rearwardbodily. This movement of the slide 55 forces the link 6l rearward,imparting similarl movement to the Lipper end of lever 62.y This lever7being pivoted at 62, has its lower end thrust forwardlaway from thetrack 65, thus 'releasing the bearing member 24 and allowing the latterto move on its pivot` 25 su'liiciently to bring'its end 73Z1 against theend 661 ofthe latch 66. The weight of the rear end .of the implement isnow transferred to thelateh 66 whose rear end co-op'erates with uwrer-ward @ad ofthe projecties 73a' ofthe bearing member '24 to fone@Stop which fer the time being prevents'any furl tlie lr'lve'liit f thebearing" member H its pivot 25. This occurs immediately afterthebeg'inning of the operation of lowering the front end of theimplement and before the latter operation was completed. In otherYwords7 the lowering of the rear end was discontinued before it wascompleted and before the lowering of the frontend was completed. Duringthe time the front end of the implement is being lowered while the rearend is held by the engagement ofthe projection 73a with the latch 66,the link 61 of course continues its rearward movementand ythe lever 63continues to move with` the link yon its pivot 62a.

The trigger 70 is thusI brought intoengagement with the'fprojectien 69and by a further movementV of the llink and lever the trigger is causedto raise the latch out of engagement with the end 73a ofV the pro`ject-ion from the bearing member 24, thus freeing the bearing member 24which now turns on its pivot 25, under t-he `influence of the weight ofthe rear end of the implement, until stopped by the engagement of a` setscrew 76carried by the vmember 24, with the rear of the frame plate 262.Vhen this occurs the yfront end of thein'iplement will have reached 4itslowerniost position and as the implement was traveling forward duringthe lowering'operation, it follows that the soil turning members willVhave been caused to enterr the .ground gradually and point first.

It will be noted on reference to `Fig. 6 that whenv the soil turningmembers are in working position7 the roller 64 is out of engagement withthe track 65, the latch 66 is heldv out ofy engagement with the forwardprojection 73 by the trigger 70,` and the th-"ust of the rear end. ofthe Iimplemer'ltis LUO carried by the set screws 76. ln the liftingoperation, the operator engages the clutch members with each other asalready described, thus causing the forward movement of wheel. A to movethe cranked portions 1G, and 19 of the axles to more nearly verticalposition. During this movement, the slide 55 is moved forward, thuspulling the link 6l Jforward. The first part of the movement of thislink is consumed in moving the roller 64 into engagementr with the track65 and during this time no movement is imparted to the bearing 24, butwhen the lost motion introduced by spacing the wheel from the track hasbeen taken up by the first part of the movement of the link, theconnections become 'operative to turn the bearing member 24 upon itspivot 25 until the parts have again reached the position shown in Fig.5. During this movement the trigger ZO is withdrawn from the projection69 and the trigger 66 thereby is permitted tol fall to the positionlshown in Fig. 5.

It will be noted that during the movement of the parts from and intotransport position the lever 50 maintains its fixed relation to theframe and that while the lever 59 partakes of the movement of the slide58, yet it does notv turn upon its pivot in such movement and that itsmovement with the slide is a slight one only. Accordingly, the positionof both levers is substantially the same whether the parts be intransport position or in working position and they are at all timeswithin convenient reach of the operator on the tractor.

8O and 8l designate springs whose rear ends are connected, respectively,to the cranks 5A and 57 and Whose forward ends are connected to` fixedparts of the implement frame. These springs balance the weight of theimplement and thereby reduce the force required to be expended in theraising of the parts.

Having thus illustrated a preferred embodiment of my invention anddescribed the same somewhat minutely without intending thereby torestrict the protection to the particular illustrated embodiment butbeing mindful at all times and wishing it to be so understood that theembodiment is merely exemplary and that changes in the details may bemade without departing from the spirit of the invention:
